Definitions

  • the invention relates to a method for treating hides or skins and tanned leather and fur with special tensides to improve the water repellent effect.
  • hydrophilic substances are used in the Avoided as much as possible in the course of the manufacturing process because they have the water-repellent effect can negatively affect the finished leather.
  • these include in particular salt-like ones Compounds and surface-active substances such as surfactants. Nevertheless, there is a complete waiver of the use of this mesh, washing and softening as well Dispersing and degreasing agents are not possible because of a sufficient and Even degreasing is necessary to produce good quality articles.
  • wet-blue material in question is preferred for reasons of rapid working through, only insufficiently degreased and was prepared.
  • wet blue materials are often of different quality and there is a need, the different wet-blue materials in one work step to a uniform end product to process.
  • Another way of reducing quality is to autoxidize what remains Natural fat in the air-facing scar layer during long-term storage, which can occur with wet-blue material (storage times are up to one year possible). Both phenomena can lead to the hydrophobizing agent being insufficient penetrate into the leather and therefore cannot fully develop its effect.
  • DE-OS 2 219 806 discloses the use of fatty acid amides as lubricants for materials with a fibrous structure.
  • the aim of greasing leather is to give the material a pleasant slimy grip and has nothing to do with the hydrophobization of leather. Rather, the greasing of leather has the aim of producing a soft leather.
  • Preferred compounds thereafter are the condensation products of the aminocarboxylic acids sarcosine, ⁇ -alanine, o-amino-benzene-carboxylic acid and ⁇ -aminocaproic acid with fatty acids of natural origin.
  • the claimed compounds are used exclusively for greasing leather that has already been retanned. With this application, less water is observed. It takes place exclusively in liquor greasing.
  • EP 0 213 480 describes oleic acid sarcoside and other sarcosides as emulsifiers for silicone oils and a process for waterproofing leather and furs with these silicone oil emulsions.
  • the use of salts of N (C 9 -C 20 -acyl) amino acids for emulsifying silicone oil in the aqueous phase during the hydrophobization is claimed. This procedure is carried out during or after retanning.
  • Amides and anilides of higher fatty acids are known in the literature as effective washing, wetting, Dispersing and leveling agents in the textile sector are described (DE 635 522) applied. Because of these extremely hydrophilic properties, they are in the frame Avoided water repellency: As with almost all water repellents all surfactants or strongly emulsified fatliquors are also water-repellent Effect (BASF, Technical Data Sheet on Densodrin S, May 1988 edition).
  • the surfactants used are sarcosides, i.e. compounds of the RCO-N (CH 3 ) CH 2 COO- type.
  • Preferred acid components are saturated and unsaturated fatty acids, and in particular the longer-chain ones in the range from 16 to 22 carbon atoms, especially oleic acid.
  • Such sarcosides support the formation of oil-in-water emulsions. Their surface activity in aqueous solution is most pronounced at a slightly acidic pH. It is therefore used immediately after incorporation of the wet-blue as laundry or brochure or in neutralization.
  • the products come in the form of their water-soluble salts, e.g. B. as alkali salts, in particular of sodium or potassium, as ammonium salts or as salts of a mono-, Di- or trialkanolamines are used, with mono-, di- or triethanolamine preferred are.
  • the amounts used are between 0.5 and 5%, preferably between 1 and 5 %, based on either the paw weight or the fold weight depending on the area of application.
  • the non-ionic alkyl polyglycosides are also effective in the areas of application described above. Because of their low foaming and their distinctive property of producing microemulsions, they are ideal for increasing degreasing. Preferred are types whose residue on the glucose unit is at least in the range C 12 -C 16 , better C 16 -C 18 or longer-chain. This residue can be saturated, unsaturated, straight-chain or branched. To avoid excessive hydrophilicity, a degree of glucosidation of 1 to 3 is preferred.
  • the alkypolyglycosides have a solid to waxy consistency. They show good properties when used together with other surfactants such as. B. the sarcosides.
  • Polyethylene glycol carboxyalkyl ethers represent further suitable surfactants for the described field of application.
  • These ether carboxylic acids of the general formula R (OC 2 H 4 ) n OCH 2 COOH are preferably suitable in the presence of a hydrophobic fraction such as C 16 -C 18 and values for n between 2 and 5.
  • the products arrive in the form of their aqueous solution, usually 50-70% by weight w. S., to Application.
  • the amounts used are between 0.5 and 5% by weight, based on or fold weight, preferably for sizes of 0.5-3% by weight, in wet-blue washing or brochure at 2 - 5% by weight.
  • All surfactants used in accordance with the invention are preferred for amounts in bulk from 0.5 to 3% by weight, for wet blue laundry or brochure in quantities of 2 to 5 % Used.
  • the surfactants are used in a known manner from the aqueous liquor.
  • the following Leather production steps are not changed. High quality is created and highly hydrophobic leather with good physical and physical properties.
  • the water repellency is carried out according to known methods and with known means.
  • Example 2 With a different wet blue provenance than in Example 1, the procedure was analogous to Example 1. A paraffin and silicone oil emulsion was used as a water repellent.
  • Example 3 The same wet blue material as in Example 3 was analogous to Example 1, but with the Water repellent based on paraffin and silicone oil.
  • the very good value for the Maeser test improved from 67,950 to 110,500 flexes.
